SFECIFICATION forming part of Letters Patent No. 318,284, dated May 19, 1885.

A pplication filed January i985.

T0 @ZZ whom, 'it ltcty/ concern,.-

Beit known that I, IIEINRIcH OCHWADT, a subject of the King of Prussia, residing at the mine called Von derl Heydt, near Saarbrcken on the Saar, in the Kingdom of Prussia, have invented new and useful Improvements in Water-Gagcs, of which the following is a specification.

This invention relates to improvements in 10 water-gages; and it consists in the novel conA struction and arrangement of parts, which are more fully described hereinafter in the speciiieation and illustrated in the accompanying drawings, in Which- I5 Figure lis a front elevation of iny improved gage. Fig. 2 is a vertical section of the same. Fig. 3 is a horizontal section. zontal section of a modification of my invention.

Similarlettersindicate corresponding parts. In the drawings, the letter A designates the head of a steam-boiler, to which is riveted or secured by screws the waterlchamber a, which is cast with a channel, h, which passes en- 2D tirely through the same, and connects with a corresponding slot or opening, t', in the boilerhead A. The outer end of t-he channel h is closed by a glass, b, which is secured to the face ofthe chamber ci by a key or keys, b, 3, and the same is best made of a semi-annular cross-section. The chamber a is drilled for the reception ofaplug or cock, j, by means of which the water can be shut off from the glass b when desired. 33 The glass Z is made of sufcient thickness to withstand the boiler-pressure, but in order to furnish means for preventing the escape of steam or water in case of breakage I provide a stuffing-plate, B,which consists of a metallic plate, c, to which is secured, by rivets g or in any other suitable manner, a lining of leather or india-rubber, d, and said stuffing-plate B is suspended at its upper end from the inside of the boiler-head A, and at its lower end it is connected with a oat, f, which maintains the stufling-plate in such a position that the water in the boiler can enter the waterchamber a without diiculty, Fig. 2. If, in case the glass b should burst, the stuffing-plate 5c B will be thrown by the escaping steam and Fig. 4 is a hori' (No model.)

water against the head of the boiler and close the slot or opening t' in the same, whereby thev further eseapeof water and steam is prevented. In order to cause the stufiing-plate to leave the boiler-head as soon as the broken glass is 5 5 replaced by another, a fine hole is pierced through the upper rivet,which, ifit is obstruct ed, must be reopened before putting in the new glass. The pressure on the stuffing-plate will be compensated through this hole, whereby 6o the iioat will be enabled to lift up the plate B.

In Fig. 4 I have shown my watergage provided with a channel leading to the face ot' the gage, and also with one leading to the side of the same, which channels are closed by flat 6 5 plates ot' glass b', and the opening or closing of both channels is controlled by a two-way plug or cock, j.

-My improved water-gage offers the advantage that the water-level in the boiler can be 7o directly observed through the glass, which com municates through its whole length with the water inthe boiler, and therefore it can never give false indications, nor is there any danger of the same becoming obstructed or stuffed up, 7 5 as is the ca-se in the ordinary water-tube.

In case the glass should burst there will be but a slight escape ot' steam and water, as the stuffing -plate automatically and promptly shuts otf the escape of the contents of the 8o boiler, and since the oat continually rises and falls with the level of the water in the boiler there is no danger to be feared from a possibility ofthejoints rusting in,and consequently the stuffing-plate will always act lpromptly and S 5 reliably.

Vhat I claim as new, and desire to secure by Letters Patent, is-

1. A water-gage consisting of the waterchamber c, which is provided with a chan- 9o nel, h, the glass b, secured to the face of the water-chamber and closing said channel, and the plug or cock j.

2. A water-gage consisting of the waterchamber a, which :is provided with two or 95 more channels, h, the glass plates b', secured to the water-chamber and closing said channel or channels, and a plug or cock, j, which opens or closes both channels.

3. The combination, substantially as hereiuroo before described, with zi stean1-boile1,oi' a wopening in bhe boiler-head, andaloat, f, which ter-gageoonsisting of a water-chamber, a, secontrols the motion ofthe stuffing-plate. cured to the boiler-head and provided with a In testimony whereof I have signed my name channel or with channels h, connecting Awith to this specification in the presence of two sub- 5 :L slot or opening in the boiler-head, the glass soi'ibing Witnesses.
